Be it known that we, Josnrn Srmw GAUNT, resident oi Manchester, in thecounty'o Lancaster, England, and HARRY DYSON, res'- ident oi'Huddersfield,England, both subjects of the Kingo Great Britain, haveinvented certain new and useful Improvements Connected with the SpindleMecha` nism of Spinning and like ir`raines,- ofv which the following isa specification.

This invention relates to improvements in continuous spinning anddoubling machines, and the chief object is to provide an: iinprovedmethod of ,mounting theV spindle whereby'the latter shall turn freelyunder the tension of the yarn or thread inA order to, impart the'requisite twist to. the; latter and 'this' whenthe nose. of aV cop isbeing wound near the topy of aspindle; afr'irther advantage of theimproved; construction isV that whenv a cop of increased lengthisto bewound' it is necessary for the spindle toA be increased in length tovan'extent that corresponds directly with the increase Vin the length; ofthe cop,l whereas in those of Aprevious constructions wherethe spindlebolster bearing` was mountedon" the fixed rail, the increasein lengthvofthe spindle had to be twice the increase in length of the. cop.

According to this Vinvention the spindle is. mounted in a single'upper'bearing which may be a plain bearing and footstep, both carried bya'brolster mounted upon theliting rail; the said `upper'y bearing may besecured to the bolster inf any convenient way-for example, by:`fricti'onal engagement-and the bolstermay-be out away,`

giving access to. the spindle andfenabling drag to be applied; and thefootstep mayv comprise a zing-,which may be capable of slight lateral'movement with' a; recessY in its undersideto receive a disc having aycentral hollow or'V recess to receive; the lowerend of the spindl'e-ashasalready beenproposedf the said discy is, heweverg, in the presentcase7 permittedy Va yslight radialA movement in the recessA in` thering` and? the latter may be held in position by. a;v helicalaspring'-arranged within the bolster: andmayhave for its: uppervv abutment theupper bearing or otherfxed'part adjacentxthereto;

J is a frame or lever mointcdaupon thebolster Bfbyi means ofpivots J1 ing with holes B5 formed diametrically opposite each othernear the lowerrend of the bolster; upon the end j of one arm `of theframe there is arranged a drag member y, whilst the end j2 of the otherarm of the frame carries the usual drag weights. The upper portion ofthe bolster is cut awayrat b affordthe'member jl access to the spin- Theportion of the spindle that runs within the bolster is of'uniformthickness and is provided with a flange A1 near its lower end; and theportion of the spindle without the said bolster tapers'slightly anduniformly towards its upper end.- The apparatuslis shown so proportionedthat approximately one third of the spindle is contained or enclosedwithin the bolster leaving the upper two Y thirds exposed: we haveobtained satisfactory resultsV with apparatus thus constructed, but wedo not wish our invention to be limited to such proportions.

The bearing member G 'comprisesV at its upper portion, a plain bearingG1for the spindle A; at its lower portion, an abutment or stop G2, againstwhich, during doffing, the flange A1 of the spindle A will come into`contact thus preventing the latter from being withdrawn fromthe bolsterB; and between the bearing G1 and the stop G2 the member is cut away, asat G3, to eX- pose the spindle to the drag member jl the remainingconnecting portion G4 acting as a support for the'spindle in oppositionto the action of the drag. The said bearing member G engagesfrictionally within Ythe upper end of the bore ofthe bolster, and it isprovided with a fiange G5 that rests upon the upper edges of the bolsterB asV shown in Figure 2.

rllhe footstep bearing ring F has a very slight lateral play within thebore of the bolster B; and is formed with-a circular recess F1 in itsunderside and within this recessthe disc F is arranged, the latter alsohaving a slight lateralA play within the recess F1 and being formed witha central hollow or recess f1 in its upper face for the pointed lowerend ofthe spindle A. Movement of the ring F is restrained by a helicalspring F2 arranged within the bolster B and having its upper endabutting against the stop G2 of the bearing member G.

In theconstruction shown in Figure 2 the foo'tstep bearing F f is shownresting upon the bottom of the bored hole in the bolster. vIn Figurer 5,however, the bolster is shown bored straight through; the lower end istapped as at b1; and a screwed plug B5 is provided to support thefootstep bearing Fv 7. It will be noted thatin this construction thebolster B is secured to the rail C in the manner already described withreference to Figure ,3, A p

The improved construction of spindle length of the spindle by an amountequal to the increase in the length of the cop. Y

With heavy spindles such as are used' for spinning coarse numbers it maybe advantageous to make the rflange A1 removable, and it may befiXed'upon thespindle after the lower' portion of the latter has beenpassed through the bolster bearing.
